To all who m itmay (7077 061%: v Be it known that l, FREDERICK D.Nu-son, a citizen of the United States residing at Moiine, in the countyof Rock island and Stateoi lllinois, have invented certeinnew and usefulImprovements in Corn He vesters,,oi which the following in spec cation,reference being" had therein to the necompenying drawing y 1 .liiyinvention relate to corn harvesters of the .xvell known vertical by Wei-h corn iscnt end conreycd real-v1.11 '1 ii binding mechanism Where itis bound into bundles While in a vertiezil position, end my inventionhasfor its object to are l to the efi'ectiveness oi? the ejectingmechanism so to place the boun d bundle properly upon a bundle ,czirrieror upon :i-conveyer to ingpiirt off 21, loader,,or ii n bundle cm 1 orloilederlis not used and the lnindles are dropped to be later she 7 edby manual labor, my device gives a p sitive impetus to the bundles asthey are discharged from the binder so thsit they fell stubbleiviird andfar removed from the path oi? the team or the machine on the next round.

The orbital movement of the point of the arm 6 is such as to bring thepoint of the arm, into the passage 1 at the proper predetermined time,and as the bundle 1s moved backward it assists in separating stalks ofthe bundle from those behind it in the way described; and then, asthebundle is ejected from the machine by the ejector arm 3, the ejector6 acts upon the top part of the bundle, which is found advantageous whenthe stalks are long, and the ejector, through its engagement with thebundle, causes the upper part of the latter to move backward oroutwardwhile the lower arm is moving the central orlower part of the bundle ina similar direction. ltmay be so related or timed asto continue itsengagement after the lower arm is released, as this will insure that theupper part of the bundle will descend sufliciently rapidly, in relationto the lower end, to have it When the corn is tall, as aforesaid, suchan ejector is necessary to effect a clean separation of the bundles andto deliver them stubbleward where they are deposited upon the ground inpositions substantially at right-angles to the line of travel. of thebarvester. i

What I claim is 1. In a corn harvester adapted to cut and to bind cornin bundles in a vertical position, the combination of a passage throughwhich corn is conveyed from the cutter to the binder, an ejector armoperative to project within said passage to discharge a bundletherefrom, and an ejector adapted to extend into said passage to engagewith the top part of the bundle, and co-operating with the ejector armto discharge the bundle, said ejector operating upon the bundle'for alonger period than the ejector arm as the bundle is discharged. I I

2. In a corn harvester adapted to cut and bind corn in bundles in avertical position,

the combination of a passage through which corn is conveyed from thecutter to the binder, an ejector arm operative to enter said passage todischarge a bundle therefrom, an ejector operative to enter said passageforward of the ejector arm to engage with the top part of the bundle andassist in separat v ing the stalks thereof from those which follow itand cooperating with theejector arm to discharge the bundle, saidejector operating upon the bundle for a longer period than the ejectorarm as the bundleis discharged.

deposited properly.

3. In a corn harvester adapted'to cut and bind corn in bundles in avertical position, the combination of a passage through which corn isconveyed from the cutter to the binder, an ejector arm operative toenter said passage to discharge a bundle therefrom,an ejector supportedon the upper end of the knotter shaft of the binder and operative toenter'said passage forward of the ejector arm to engage with the toppart of a bundle and separate its stalks from those which follow it, andco-operating with the ejector arm to discharge the bundle.

' 4. In a corn harvester adapted to cut and bind corn in bundles in avertical position, the combination of a corn is conveyed-from thecutter-to the hind,- er, an 'e jector arm operative to enter saidpassage to discharge a bundle therefrom, an ejector located above theknottermechanismf and operative simultaneously with said ejector arm andentering said passagetherewith forward of the ejector arm to engage withthe top part of the bundle to assist in separating its stalks from thosewhich follow it, andco operating with the ejector arm to discharge'thebundle, said ejector operating upon the bundle for a longer period thanthe ejector arm. J

5. in a corn harvester adapted to cut and convey corn in a verticalposition to a bind ing mechanism, the combination of a passageway, guidearms leading stubbleward from the binder, an ejector arm operative toenter said passageway to discharge a bundle therefrom rearward andstubbleward between said guide arms when the bundle is bound, and anejector locatedabove the knot-.

.ter mechanism and'operative to enter said guide arms to discharge saidbundle at an angle to the-line of advance of the harvester. 6. In a cornharvester adapted to cut and convey corn in a vertical position to abindpassagethrough which ing mechanism, the combination of apassa'geway, guide arms leading stubblewar d' from the binder on eachside of said passageway, an ejector arm operative to enter saidpassageway to discharge a bundle rearward and stubbleward between saidguide arms when the bundle is bound, and an ejector located above theknotter mechanism and at the upper end of the knotter shaft and-actingto engage with the top part of thebundle and co-operating with theejector arm and, i

the guide arms to discharge the bundle stubbleward. 1 v I 7. In a cornharvester adapted to cut and bind corn in bundles'in a verticalposition, the combination of a passage through which corn is conveyedfrom the cutter to the me i binder, an ejector arm operative to entersaid passage to discharge a bundle therefrom, a crank arm mounted on theupper end of the knotter shaft of the binder, an ejector pivotallysupported on said crank arm and operating to enter said passage forwardof the ejector arm and simultaneously therewith to support the top of abundle as the latter is formed and bound and co-operating'with theejector arm to discharge the bundle. 10

In testimony whereof I affix my signature, in presence of tWo Witnesses.
